Public bug reported:
The USB printer discovery code falls back to the /dev/usb/lp# naming
scheme if it cannot find the character device file /dev/usblp0 or
/dev/usb/isblp0.
However:
- Current Linux kernels + udev use /dev/usblp#
- Current udev removes device nodes which do not exist any more
The practical effect is that, if you have more than one USB printer and
unplug the one that has been assigned to usblp0, cupsys is unable to
find any of them.
That's not nice, to say the least.
** Affects: cupsys (Ubuntu)
Importance: Undecided
Status: Unconfirmed
